Abstract

The invention relates to an exhausting silencing system of a mute generator unit, in particular to a combination type exhausting silencing system, belonging to technical field of a silencing system for an internal combustion engine. The invention is characterized in that: the combination type silencer comprises a primary silencer and a secondary silencer; wherein, an air outlet pipe of the primary silencer is connected with an air inlet pipe of the secondary silencer by means of a flange; both the primary silencer and the secondary silencer are arranged in a partition bin. A capacity expansion tube section is arranged at an inlet end of the primary silencer; a flexible tube section is arranged in the exhaust tube. The invention has the advantages of increasing total work volume of the silencer, improving silencing result, having flexibility of choosing a plurality of technical proposals, lowering total noise level of the generator set, obviously lowering noise and improving reliability of installing the silencing system.

Description

technical field [0001] The invention relates to an exhaust silencing system of a silent generator set, in particular to a combined exhaust silencing system, which belongs to the technical field of internal combustion engine silencing systems. Background technique [0002] In the prior art, a traditional generator set driven by an engine usually adopts a first-stage exhaust muffler, which can generally meet the requirements. In some occasions where noise is limited, manufacturers often make the casing of the generator set closed to block noise, and use some high-end exhaust mufflers to eliminate noise, thereby forming a silent generator set. However, the internal structure of the high-grade exhaust muffler is complicated, the cost is high, and the supporting model is single. [0003] On July 19, 2006, the State Intellectual Property Office of China disclosed a utility model patent for a "muffler for a low-noise generator set" with the publication number CN2798401. B), each ...
